Study Notes
Eclipses
- Almost identical eclipses occur after 18 years and 11 days, known as the Saros Cycle.
What Is an Eclipse?
- An eclipse involves the Sun, Earth, and Moon.
- When they align, one object can be obscured from the viewer, known as an occultation.
- If the passing object is smaller, the third object is only partially hidden, known as a transit.
History of Eclipses
- In ancient times, people interpreted eclipses as a sign that the gods were angry, a bad omen.
- The word "eclipse" comes from the Latin "eclipsis" from the Greek "ekleipsis", meaning "to fail to appear" or "to leave".
Types of Eclipses
- There are two types of eclipses: solar and lunar eclipses.
- Solar eclipses occur when the Moon passes between the Earth and the Sun.
- Lunar eclipses occur when the Earth passes between the Sun and the Moon.
Solar Eclipses
- In 2024, a total eclipse will be observed over the continental US, the eastern part of Canada, and Mexico.
- Totality will last for about 3 to 4 minutes depending on location.
- A partial solar eclipse will fall around the Pacific and other areas of South America.
Solar Eclipse Facts
- When the Moon completely blocks the Sun, it's called totality, which lasts around 7.5 minutes.
- As a result of the Moon and Earth's movements, totality doesn't last long.
- Solar eclipses cause strange changes around us, such as temperature drops, breeze disappearance, and shadows appearing different.
- They affect animals in strange ways, causing them to behave as if it's nighttime.
Types of Solar Eclipses
- There are four types of solar eclipses: partial, total, annular, and hybrid.
- Partial solar eclipses occur most frequently (35%).
- Annular and total solar eclipses have a 33% and 27% chance of happening, respectively.
- Hybrid solar eclipses are rare, occurring only 5% of the time.
Hybrid Solar Eclipses
- Hybrid solar eclipses are rare, occurring only 7 times in the 21st century.
- They are so rare that only 7 eclipses of this type occur in this century.
Total Solar Eclipse
- A total solar eclipse happens when the Moon's dark silhouette completely covers the Sun's bright light.
- It occurs in places where the umbral shadow is cast, known as the path of totality.
- The path of totality moves across the planet at around 2,253 km per hour (1,400 mi per hour).
Annular Solar Eclipse
- An annular solar eclipse occurs when the Moon and Sun are exactly in line, but the Moon appears smaller than the Sun.
- This happens when the Moon is further from Earth or the Earth is closer to the Sun.
